ELECTRODE HOLDER.

Application filed May 21,

' This invention relates to new and useful im rovements in an electrodeholder.

ne object of the inventlon is to provide an implement of the characterdcscribedc specially designed for the purpose of bolding an electrode tobe used in electric welding and the invention comprehends an 1mplementwhereby the electrode.may be securely held while in use and may bereadily to released.

Another object of the invention resides in the provision of an implementof the character described which may be easily handled in applying anelectrode to the work.

A still further feature of the invention resides in the provision of anelectrode holder which is'of very simple construction and may be cheaplyand easily produced.

l Vith the above and other objects in view the invention has particularrelation to certain novel features of construction, operation andarrangement of parts, an example of which is given in this specificationand illustrated in the accompanying drawings,

263 wherein Figure 1 shows a side elevation of the implement shownpartly in section.

Figure 2 shows a side elevation thereof, partly in section, taken atright angles to at the view shown in Figure 1.

Figure 3 shows a transverse sectional view of the implement, taken onthe line 3-3 of Fi e 1-, and

igure 4: shows an end view thereof.

Referring now more particularly to the drawings, wherein like numeralsvof reference designate similar arts in each of the figures the numeral1 esignates a tubular handle or grip member formed of suitable toinsulating material. Fastened to one end of the handle there is a guard2, preferably circular in contour and also formed of insulatingmaterial. F astened to the guard end of the handle there is a tubularshank t5 4: whose outer end carries a suitable bracket 5 whichterminates in the overturned fixed jaw 6. In the grip 1 there is aU-shaped bracket 7 which is preferably secured to the grip by means of asuitable set screw 8 and so whose ends 9 and 10 are overturned intoalignment and the latter of which is formed with'a bearing 11. AU-shaped clamp 12 is fitted over the overturned end 9 and securedthereto by means of a set screw 13 68 which passes through said clamp aswell as through the overturned end 9 and the side posed between theoverturne lever 16 and whose respective ends surround 1927. Serial No.193,150.

arms 14 ofsaid clamp are overturned and embrace the end 9 so as toprevent the clamp 12 from turning or pivoting on the set screw 13. Anelectrical conductor 15, form-- ing one side ofthe electrical circuithas its inner end clamped between the clamp 12 and the overturned end 9.

7 and whose other end projects through an elongated slot 17 in thehandle 1, said proj ecting end being formed with a thumb plate 18 bymeans of which the lever may be moved. a

A stem 19 has a pivotal connection to the lever 16 and works through theshank 4: and its outer end is provided witha movable jaw 20. There is acoil spring 21 interend 9 and the the opposing ends of the screw 13 andthe rod 19 respectively by means of which said spring is retainedagainst displacement.

0ne end of the electrode 22 to be held may be inserted between the jaws20- and 6 and when making this insertion the lever 16 should bedepressed to draw the movable jaw from the fixed jaw and ;when releasedThere is a lever 16, one end of which is pivoted to the bracket,

the pressure of the spring 21 will operate to move the movable jaw 20into clamping relation with the electrode. The electrode may then bebrought into operating relation with the work, the latter forming theother side of the electrical circuit.

While I have illustrated one form of the implement, which I now considerthe preferred form thereof it is obvious that mechanical changes may bemade and equivalents substituted for the parts shown and I reservethe.right to make such changes as may be found desirable so long as Ikeep within the scope of the appended claims.

What I claim is l.' An implement of the character described including atubular handle, a plate like guard fixed to said handle, -a tubularshank attached to the handle at one end, a

bracket fixed to the other end of said shank which terminates in anoverturned fixed jaw, a U-shaped bracket in said handle whose ends areoverturned into alignment gated slot in said handle, a stem workingthrough said bearing and handle and whose other end is provided with amovable jaw and a coil spring operable against said lever and normallytending to hold movable jaw in coogerating relation with the fixed jaw.

2. n implement of the character described including a tubular handle, aplate like guard fixed to one end of said handle, a tubular shankattached to the guard end of the handle, an overturned fixed jaw car-.ried by the free end of theshank, a U-shaped bracket in the handlewhose ends are overturned into alignment one of said ends being formed'with a bearing, a U-shaped clamp fitted over the other end of saidbracket and having side arms which clamp said bracket said slot, a stemWorking through said bearing and shank, a movable 'aw fixed to said stemand confronting sai fixed jaw, said stem being pivotally connected tosaid lever and a yieldable member interposed between said bracket andlever, Y

In testimony whereof 1 have signed my name to this specification.
